Are toric lenses safe?

Toric lens implants pose no additional medical risk and are perfectly safe. Because they are still a single-focus lens, they do not introduce halos or other additional optical side effects. They do not require the cataract surgery to be performed any differently and do not effectively lengthen the surgical time.

Should astigmatism be corrected during cataract surgery?
